Are VoIP clients supposed to set TOS to minimum delay?
Hi all
Tcpdump shows Kphone UDP traffic has not set as
minimum delay traffic!
This is a tcpdump from My-IP to Other-IP:
13:07:14.704501 IP (tos 0x0, ttl 64, id 813, offset
0, flags [DF], proto: UDP (17), length: 120)
My-IP.32784 > Other-IP.10384: UDP, length 92

Here TOS is 0x0, that is, normal traffic! Are VoIP
clients supposed to set TOS to minimum delay? Is there
any reason for this? Or is...
